Brillouin optical time domain analyzer DSTS Distributed fiber optic strain strain sensor BOTDA1000
Ho lekanya Molao-motheo
Ho ipapisitsoe le phello e khothaletsoang ea Brillouin ea ho hasanya, Brillouin optical time domain analyzer BOTDA e sebelisa mehloli e 'meli ea leseli la laser e mosesaane, e leng pompo (pulsed optical signal) le probe (continuous optical signal), ho kenya matšoao a mahlo lipheletsong tse peli tsa ho lemoha fiber, ho lekanya le ho lemoha matšoao a optical qetellong ea pulsed optical ea fiber e utloang, le ho etsa ho fumana le ho sebetsa ka potlako ea data.
Molemo oa theknoloji
· Tekanyo e phatlalalitsoeng ea sebaka se selelele sa bolelele bo bolelele, ka bolelele bo boholo ba 60km.
· Thempereichara, khatello le tekanyo ea spectrum
· Tekanyo e nepahetseng, e tsitsitseng le e tšepahalang
· Khoutu e felletseng, e sa angoeng ke ho feto-fetoha ha matla a mohloli oa leseli, fiber microbending, tahlehelo ea fiber hydrogen, jj.
· Fiber ea puisano ea mokhoa o le mong e ka sebelisoa ka kotloloho ho sensor, 'me "phetiso" le "kutlo" li kopantsoe.
